Car Engine Whines When Cold

If you’ve noticed your car engine whining when it’s cold, you’re not alone. This is a relatively common problem that can be caused by a number of different factors. In this article, we’ll discuss the most common causes of this problem and provide some tips on how to fix it.
What Causes an Engine to Whine When Cold?
There are a number of different factors that can cause an engine to whine when it’s cold. Some of the most common causes include:
- Loose or worn belts: When belts become loose or worn, they can slip and cause a whining noise. This is especially common in cold weather, when the belts are less flexible.
- Bad pulleys: Pulleys are responsible for guiding belts around the engine. If a pulley becomes damaged or worn, it can cause the belt to slip and whine.
- Power steering pump: The power steering pump is responsible for providing hydraulic pressure to the power steering system. If the pump is damaged or worn, it can cause a whining noise.
- Alternator: The alternator is responsible for charging the car’s battery. If the alternator is damaged or worn, it can cause a whining noise.
